Hello,Michael

    Now when I build the target ,I can get the My_Application.out.I want to know how to build the My_Application.exe?or how to change My_Application.out to My_Application.exe?

because only the exe file can run in the arm7 with uclinux system.

   Thank you very much!

Hi Lianzi,

The format of the output file is probably determined by the linker, so you should take a look at the Script Linker VI and modify the commands it sends to the linker.

Hello,Professor,Thank you for your help again.

      Now i can build the project without any error,but the file build form the project can't run  in the arm7 with uclinux when i dowmload it.I don't know why.

My complier flags is as follows:

-I./  -DCHeadless=0 -elf2flt -Dlinux -fno-strict-aliasing -fno-common -fomit-frame-pointer

My linker  flags is as follows:

-mcpu=arm7tdmi -mstructure-size-boundary=8 -mlong-calls -Wl,--gc-sections -Wl,-static  -nostdlib -Wl,-static -L"%s" -Ttarget.ld

And i know there is a new embedded tool for arm ,which is called LabVIEW Embedded Module for ARM Microcontrollers,I find what i need to do is in the tool,but i alread bought the embedded development module? how can i do for it?

Hi,

The LabVIEW Embedded Module for ARM Microcontrollers uses a differentOS than uCLinux, and it supports a specific set of ARM MCUs <http://zone.ni.com/devzone/cda/tut/p/id/7066>.This might be a good option for you, but it will require following the tutorial here: http://zone.ni.com/devzone/cda/tut/p/id/7152.

Regarding the uCLinux issue, I recommend that you manually walk through the process of compiling, linking, downloading, and running a hand-written C application ("hello world" ) and verify that it runs correctly. Then, compare that process with the process automated through the plug-in VIs in LabVIEW.

Hi Kudos

I am currently trying to do as you and make a linux application using gcc-linux on cygwin on a windows platform. One thing is stopping me and that is the same linker errors as you get. Could you help and tell me how you resolved them?

I based my linux target on the unix console target and installed a gcc-linux toolchain on cygwin. My application is very simple and just writes "Hello World" to standard out. The app can compile using the gcc (win32 app), but the linker errors comes when using the gcc-linux compiler.

Thank you!
